British Airways Plc applied on 21 June 2017 to wet lease nine Qatar registered Airbus A320 or A321
aircraft, registrations to be advised, between 1 and 16 July 2017, and for additional periods, yet to be
defined, for a maximum of two months.
The application has been made on the grounds that the lease is justified on the basis of exceptional
needs (Article 13(3)(b)(i) of Regulation (EC) No 1008/2008) to enable British Airways to continue
passenger operations in light of planned operational disruption by its Mixed Fleet cabin crew.
